it is indeed very problematic to let a client send a message only because it claims to be a certain sender. Any client can do that and given the fact that there are dictionary attacks taking place all the time you shouldn't do that. As I understand it the client you want to connect to your server is not capable to do SMTP AUTH. Will you be able to identify the client by its static IP? Will it connect comming from a known IP space e.g. a VPN IP range? Or is it able to use a TLS client certificate? If we find a criteria we can solely attribute to your client will have something the server can trust in. p@rick -- All technical questions asked privately will be automatically answered on the list and archived for public access unless privacy is explicitely required and justified. saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/>
